Abstract: A system for removably connecting and interfacing an electronic portable audio device with an otherwise substantially conventional vehicle audio system to facilitate listening to playback of electronic music files stored on the portable audio device. A docking connector for receiving the portable audio device is physically and operatively integrated into a shared housing with the vehicle audio system, and a single set of controls is provided for controlling operation of both the portable audio device and all conventional components of the vehicle audio system. A removable interface module allows for adapting the system for use with differently designed portable audio devices.
